How to return the network to the container?

Question

ubuntu

Good afternoon.
I set up openvpn, as a result, pings to the container disappeared, although it connects via ssh and pings from the container itself go.

Answer 1

Fail2ban does not have its own ip?
tail -n 100 /var/log/fail2ban.log |grep Ban
